SVG Fundamentals
This example demonstrates the fundamental building blocks of SVG graphics, showing a simple circle and a navy diagonal line rendered inside a 960 by 500 pixel viewport. The code uses plain SVG elements (`<circle>` and `<line>`) with basic XML attributes for position, radius, and stroke, embedded directly in an HTML page. It relies on the browser’s native SVG support and requires no external libraries, serving as a minimal starting point for creating vector graphics with CSS and JavaScript.
